Customer Question

I have a Rheem Ecosense heat pump water heater, model #JPYA A050J13. The unit does not heat water in heat pump or emergency heat mode. The lights in the panel come on but the fan and pump don't seem to cycle on.

The problem in this case would be either a defective temperature sensor, or a bad printed circuit card most likely, 90% chance of that, and a 10% chance that the high limit safety switch has failed.

Tell me a lot about your technical background and capabilities so that I can coach you most appropriately.
